Eight coherent channels.Zero integration project.

ApexSDR is a wideband coherent receiver built around one idea: phase alignment should be a property of the hardware, not a months-long systems project. Eight receive channels, 100 MHz of instantaneous bandwidth each, full-rate streaming over a single 40GbE link — and when eight channels aren't enough, boards chain into one coherent array with SMA jumpers.

Coherence that scales by cable

Multi-box phase coherence is normally where coherent-array budgets go to die — distribution amplifiers, timing switches, and an integration schedule of their own. ApexSDR carries reference, LO, and PPS in and out natively: chain boards with SMA jumpers and the stack behaves as one instrument. Thirty-two coherent channels is a parts order, not a program.

Ships with Apexia Fabric

Every unit includes Apexia Fabric — the software stack that turns aligned samples into working instruments. Ready-to-run reference designs for direction finding, TDOA, and passive radar; live debug and visualization; and a C API for building your own processing. No Vivado, no VHDL — aligned samples in minutes, not weeks.

Fabric is built by the same bench that ships our radar DSP cores — the pipelines are the product, not a demo.

Early access

First units go to a small set of founding instruments — research groups and teams who want eval hardware with white-glove bring-up from the engineers who built it. Join the list, or if you're building an instrument now, talk to us directly.
